PRINTING-FRAME.

Specification of Letters Patent.

Patented June 22, 1909.

Application filed June 3, recs. Serial Flo. 5236, 286.

T all whom it may concern:

Be it known that I, BENJAMIN D. MILLER, aw

a citizen of the United States, residing at ooster, in the county of l'Vayne: and State of Ohio, have invented certain new and uselul lm rovements which t re followin r is a specification.

improvement in a printing frame, and is particularly adapted for the use of photographers, although I do not-limit myself to thrssp'ecific use, as it may just as well be used for other purposes.

It has for its object the provision of means for easily and quickly removing the back.

It has for its further object the employment of latches which may be automatically released from engagement with the back to allow the inspection of a part of the print, or to allow the removal of the entire back as may be desired.

It is well-known that during printin it is often desired that the print be inspecte and considerable time is wasted in this operation, and it is for the saving of time and labor that I construct my frame as will be more clearly described and shown in the drawings forming a part of this specification, in which Figure 1 is a view showing the back in position Fig. 2 shows a section of the heel:

, and Gare details of the latch mechanism.

The frame is constructed in the well known manner havin the side bars 1 and the end bars 2. The bac 3 is made in two sections hinged as shown at 4, and on each section there is a bow spring 5. These springs are provided at each end with slots 6, which The heads of the SQZNV are somewhat wider than the slots in s ring, and in this way secure the springs to tlie back, but still allow a sliding movement tension. 0n ofthese springs 5 I provide at upper surface is hevelerl' as re drawings and presents a ose of which will herein after be more clear y described. On each of the side bars I secure latches 10, which engage the bow springs 5. These latches are eecured in position by means of the screws 11, and one edge is slightly turned up as shown at 12 so that the latch will easil ride over the ed e of the s ring. This lateis also provi ed with a mob 13 for engaging the fingers for operating the same.

of the springs when put under the top of each lug 8 whose in Printing-Frames, of

y g position. My-mvention re ates to a new and useful Under each of the latches the bar is cut as shown at 14, and has a depression 15 somewhat deeper than the rest which re ceives the coil spring 16, which operates the latch. l /hen in position this spring will surround the screw 11 for holding the latch in .The coil spring 16 is Wound so as to leave the straight ends 17 and 18, the end 17 entering a hole or opening i9 to the side: of the depression 15, and the end 18 engaging a pin 20 on the under side of the latch. H desired I also provide the edge of the cutaway portion with a re-inforcing metal strip 21, which will always present a straight edge against which the pin 29- will abut to limit the movement of the latch.

With the various arts assembled, the op eration will be as fo lows :T.he back being in position, the latch is turned so as to engage the bow spring 5 and is all wed to ride over the lug 8 and engage the shoulder 9. in this position the coil spring 16 will be under tension. To disengage the latch the bow s ring is slightly depressed so as to release tne latch from the shoulder 9, and by means of the coil spring under tension the latch will swing around out of engagement with the bow spring. If it is desired to inspect the print only one latch is released and one sectien of the back opened, but if it is desired o remove the print release both latches and remove the back.

it is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and see c of my inven; tion, and hence I do not wish to be limited to the exact construction herein set forth, but:

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A printing frame having a removable back and meanstor securing the back consisting of bow springs secured to the back and latches for engaging the bow springs secured to the frameby means of screws, springs surrounding the screws engaging pins on the latches and adapted to be put under tension so as to automatically operate the latches when disengaged from the bow springs.
